Get the starter draw tested. Sounds much more like a slow starter to
me, unless you have serious compression leakage around those new glow
plugs it should start like it did before.
Don't wait until it locks up....

Several months ago, I installed 6 new glow plugs in the SDL. Since
then, when its cool, below 50F or so, I have to glow it for 3 or 4
30-second cycles to start it without "grinding" starter. Glow
light gives normal indications, fuse is good/new (yes, it really is
- good power (12v) on both sides of fuse), relay clicks at 30
seconds, continuity check of all plugs is good. 'Does same way
with another good relay. Plugs are obviously heating some -' just
takes longer/several times when engine is cold. When it starts,
all cyls fire evenly with nice, smooth idle. 'Seems that when it
gets warm enough to start, all cyls have warmed evenly. 'Just
realized something I haven't done yet - check voltage at each of
the 6 relay pins during the 30-second cycle. Always before, 'cept
when plugs are bad, it started with just a touch of the starter
switch to START.
When I replaced the glow plugs, I did not ream the holes; suppose
carbon build-up is keeping the plugs from heating as rapidly or as
well as it normally has? 'Spose my need for additional glowing is
due to carbon build-up?
